Carp designated for assignment; Holland off DL

HOUSTON -- The Rangers were forced to designate first baseman Mike Carp for assignment to make room for pitcher Derek Holland on Saturday.

The Rangers, by rule, were forced to take Holland off the 60-day disabled list after his medical rehab assignment expired on Thursday and add to him to the active roster. The Rangers also needed to add him to the 40-man roster.

Carp was the move because the Rangers are committed to looking at Ryan Rua at first base for the remainder of the season. Carp was claimed off trade waivers from the Red Sox at the beginning of August, but was just 5-for-40 in a part-time role at first base.

"He didn't really get it going but that didn't come into play," manager Ron Washington said. "With all the young kids we want to see, there just wasn't a whole lot of at-bats for him. We needed to make a roster move. It's unfortunate because he is a pro."

With Carp gone, the Rangers are without two of their left-handed bats as Jim Adduci is on the seven-day concussion disabled list and not eligible to come off until Friday.
